Operational oceanography provides forecasts or near real time information of ocean conditions. This information can be used to assist in fishing, oceanic oil rig position or navigation so that these entities are prepared for poor or dangerous conditions and can take appropriate action. Sea level measured from Jason-3 is important for these forecasts as it provides information on what the current ocean conditions are and also the wave height.

Marine wildlife, such as penguins and sea turtles, can be tacked from satellites using ARGO transmitters, along with and measuring currents and sea surface temperature from other ocean observing satellites. Knowing the currents and temperature help with understanding where marine wildlifes’ feeding grounds are and if they are being impacted by climate change.

Coastal areas are subjected to erosion from waves breaking on shore and storms. Satellite altimetry from the Jason series can provide information on sea level rise, which can be used in planning beach renourishment to combat erosion.  To further understand coastal processes and monitor coastal erosion a new satellite mission, SWOT, will provide a finer resolution than what the current altimeters can provide.

Jason-3 launched 17 January 2016. It is the 4^th in a series of altimetric satellites, starting with TOPEX/Poseidon in 1992, that is jointly operated by NASA and CNES along with NOAA and EUMETSAT. Jason-3 continues the legacy of measuring sea level and understanding climate change. It is also important for operational oceanography, which is used for marine meteorology.
